What is a sketch icon? I know how to select a screenshot for each sketch:
- At the top-center, there are 3 clickable icons:
, 
, </>. - When we click the 1st 1 , a red clickable button “Edit” shows up when we’re signed in.
- And when we click that button, there’s a screenshot icon
as 1 of the “Edit” options.
Well, we can create extra tabs by hovering the mouse at the same row as the default tab “mySketch”.
A 
sign shows up for us to create extra tabs.
